View Full Version : Does a plant take after pollen or seed parent more?

I have a general question about whether a plant tends to take on more of the characteristics of the pollen or seed parent. Does one tend to pass on physical characteristics better than growth habits?
For example:
If a pollen parent is sequential and a the seed parent is not, will the plant bloom sequentially?
What about vice versa, if the seed parent is sequential and the pollen parent is not?
Thanks in advance,

Ah, how rarely we come across such an easy to answer question...

The progeny take on greater characteristics from the pod parent.

Steve, would you explain the fact more on a genetic point of view ?? I am also curious as well ! Thanks !! :wink:

Genes for a lot of things (many color pigments, for example) are carried in the plastid genome. Yes, the little organelle has its own genome. So do mitochondria. The plastid and mitochondrial genomes are only enherited from the pod parent.

Now, I haven't been able to get a straight answer on other phenotypes, like size and form. Those are probably encoded in the nuclear DNA. So it wouldn't matter which parent was pod or pollen.
